I MPR QVEMENT lN OI L-STOVES.

Specification forming part of Letters Patent No. 219,685, datedSeptember 16, 1879; application filed July 12, 1879.

To all whom it may concern:

Be it known that I, ABNER BURBANK, of the city of Rochester, county ofMonroe, and State of New York, have invented a certain new and usefulImprovement in OiLStoves;

and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, in which- Figure I is a central vertical section of the stove.Fig.2 is aplan with the heating-drum removed. Fig. 3 is an elevation ofthe. wicktube arrangement. Fig. 4is a detail sectional View, showing themethod of insertingthe burners in the wick-tubes.

My improvement relates to certain devices in an oil-stove; and consistsin the construction and arrangement hereinafter specifically set forth.

The oil-tank is removed some distance from the stove, and the oil is fedto the burners automaticall'y in a manner somewhat similar to that inthe German student-lamp. The oiltank consists of the open-toppedreceptacle A and an inverted fonnt, B, which rests in the receptacle.The fount has an open mouth or neck, a, and a valve, 1), so arrangedthat when the fount is inserted in the receptacle the valve is opened,and the oil can then flow down. 0 is an oil-pipe extending horizontallyfrom the oil-tank any suitable distance, according to the number ofseparate stoves to be usedwith the same oil-tank. D D are Wick-tubes,made preferably of cast metal, situated in pairs at right angles and onopposite sides of the oil-pipe 0. They are connected with. the oil-pipeby short lateral pipes c 0,.the outer ends of which open into thewick-tubes, while the inner ends connect with the main oil-pipe by asuitable crosshead or elbow. This allows the oil to flow from the mainoil-pipe into the wick-tubes. The bottom or outer ends of the wick-tubesare made closed or sealed, so that no oil can escape there; but the topsare left open for the attachment of the burners.

The wick-tubes are preferably made of the curved form shown, the bottompart being horizontal and the top part vertical.

Where more than one stove is to be used the oil-pipe O is extended, andtwo or more pairs of the wick-tubes are connected therewith at suitabledistances apart, as shown in Fig. 2.

E E are the burners which hold the wicks. They are short flat tubeshaving the wicks placed therein, and are provided with the usualspur-wheels for raising the wicks. The lower ends of the burners arefitted to be set accurately into the open tops of the wick-tubes,

V and require no other fastening. They can be removed and replaced atpleasure with the Wicks attached.

The closed wicklubes form" receptacles to hold verysmall quantities ofoil, which is fed automatically thereto by the oil-pipe O, the quantitybeing just sufficient to support proper combustion, and by this meansthe great body of oil is removed from the stove and cannot be aifectedby heat.

G is the heating drum or cylinder, which is located above the burners,and is of usual form. In the drum are cones d d, which cover theburners, and two chimneys, f, which convey the heat upward and dischargeit through the open top of the drum. Beneath the cones is a perforatedplate, g, for breaking the currents of air and properly feeding the sameto the blaze.

The stove may be set upon a tray or other suitable support.

The use of the separate wick-tubes D D, having closed lower ends,enables the oil to be fed from oil-pipe 0 directly beneath the stove andproperly supply the combustion without danger from heat, as the quantityof oil in said tubes is always small, and the great body of oil isremoved to a safe distance. In this form they are also convenient forthe insertion and removal of the wicks.

The use of two or more sets of the wicktubes at suitable distance apartenables two or more separate stoves to be used, fed from the singleoil-pipe O, and supplied from the single oil-tank A B. This isespecially convenient for restaurants, 850., where several of the stovesare necessary.

In ordinary oil-stoves each stove has to have an oil-fount of its own.

The oil-tank A B, the oil-pipe O, and the wick-tubes D D all form onecomplete and iiitegral device, so connected and arranged that they canbe lifted and handled together.

The wick-tubes by being arranged on opposite sides of the feed-pipe, andby projecting below the same, form feet or supports to retain thefeedpipe in a horizontal position, and by extending outward, as shown,they form a broad base, which prevents overturning of the reservoir andpipe. By curving inward at their top they enable two burners and twochimneys to be used with each heating-drum, which is essential toproduce sufficient heat for eookin g.

Having thus described my invention I do not claim, simply and broadly, afeed-pipe extending from the oil-tank and provided with burners on itstop; but

I claim- In an oil-stove having the self-feeding reservoir B andfeed-pipe 0, one or more pairs of wick-tubes, D D, arranged on oppositesides of the feed-pipe and connected therewith by lateral pipes 0 c,said wick-tubes being curved,

ABNER BURBANK.
